  • Recent primary concern for the design of high performance heat exchanger and highly integrated electronic equipments is to develop an active and creative technologies which enhance the heat transfer without obstructing the coolant flows. In this study, we found through the LDV measurement that the gaseous cavitation induced by ultrasonic vibration applied to the CO$_2$saturated water in the square cross-sectioned straight duct flow enhances the turbulence much more than the case of non-ultrasonic or normal ultrasonic conditions without gaseous cavitation does. We also found that gaseous cavitation can enhance effectively the turbulent heat transfer between the heating surfaces and coolants by destructing the viscous sublayer.

  • This study notices that all religions in Central Asia from the fourth century through seventh century C.E. provided considerable hands in keeping a uniform unity through a process of assimilation, although art and architecture were greatly stimulated by the creative genius of the many people. The study thus intends to argue that the common ideas of rituals and primitive forms of religious shrines lead the square-based layout of Buddhist shrines the unity and universality in the architectural products of particular regions or epochs: i.e. the "square-based plan" in Buddhist temples of Central Asia was a significant prototype in the synthesis with pre-Buddhist architectural models and Buddhist universal ideas. Thus, this thesis notes that they did not lose the universal principles of the Buddhist shrine plans due to ritual functions, and even there have been never differences from pre-Buddhist building models remarked by the periods and the venues in which they were produced, although there had been continuous evolutions and adaptive transformations in the local tastes of religious architecture. Accordingly, this study discusses how such plans in Buddhist architecture had been consistently produced within that regional style also representative of the local idioms of architecture, and how they were adopted in the sites, founded on the composition of ritual functions. The foreign architectural cultures were selectively chosen getting along with local building types of each site according to each taste for architecture as a result.

  • Global warming is affecting all industries, and has been applied very quickly in the energy sector. Existing in all countries around the world by using fossil fuels to minimize environmental changes are developing a new alternative energy sources. Among the emerging alternative energy, using solar energy technology is applied across the industry, but the maintenance and repair to integrate solar cells and has been a problem occurs. To prolong the life of cells integrated on a solar cell is exposed when the non-eye, etc., when not integrated by the solar cells should not be exposed. In order to resolve these contradictions, a square solar flower of the biological mother was developed by using TRIZ technique(6SC).

  • This paper is a study on the design of the gilt-bronze sarira caskets discovered in 1959 and 1996, from a east and a west three-story stone pagodas in Gameunsa Temple site which was built in 682. One of the most interesting discoveries is the ceiling with Bokdu(覆斗) design which can be seen in Dun-Huang grotto of China, reflected upon the ceiling structure of the cover (outer casket) and the square box (inner casket). The structure of these sarira caskets, as art crafts, directly represents architectural structure of Dun-Huang grotto that was made during the early T'ang period of China. Moreover, the sarira caskets are decorated with ornate designs and these designs also can be seen on the murals of Dun-Huang grotto. Accordingly, those sarira caskets tell us creative ability and international taste of Silla's craftsmen. By tracing the origin of structure and design pattern of the sarira caskets to Central Asian and Chinese architectures, it is able to understand international style of the sarira caskets of Gameunsa Temple site.

  • Purpose: The purpose of this study was to determine the effects of different intensity of aerobic exercise for four weeks on cardiovascular risk factors, reactive oxygen, and antioxidant enzymes in old mice. Methods: Eighteen male C57BL/6 mice age 18 months were randomly classified into the control group (n= 6), the moderate intensity exercise group (n= 6), and the low intensity exercise group (n= 6). The training groups performed the aerobic exercise twice daily for 20 minutes, five days weekly for four weeks. Data were analyzed using descriptive statistics, analysis of variance (ANOVA), the Chi-square test, and the Tukey's test with the SPSSWIN 21.0 program. Results: In this study, among the risk factors of cardiovascular disease, blood sugar (BS) (p= .023) and total cholesterol (TC) (p= .001) were significantly different between the moderate intensity exercise group and the control group. Additionally, there were significant differences in the reactive oxygen malondialdehyde (MDA) (p= .001), the antioxidant enzymes superoxide dismutase (SOD) (p< .001) and glutathione reductase (GR) (p= .015) between the moderate intensity exercise group and the control group. Conclusion: This finding suggests that moderate intensity aerobic exercise promotes the activity of antioxidant enzymes and lowers cardiovascular risk factors in older mice.

  • Consumers' need for uniqueness reflects individual differences in counterconformity and related to the attitude toward brands as well as purchase behavior. To understand the relationship between consumer's personal characteristics and purchase behavior, the study investigated the effect of consumers' need for uniqueness and clothing interest on the brand consciousness, loyalty and purchase intention. Survey was utilized to collect the data and subjects were 271 college students. Measures consisted of five main constructs: Consumer's need for uniqueness, clothing interest, brand consciousness, brand loyalty, and purchase intention. The measurement and structural models were evaluated using PRELIS 2 and LISREL 8.53. Consumer's need for uniqueness was confirmed to have three constructs: creative, unpopular, and avoidance. The researcher tested Model 1 and developed five other models-Models 2 through 6-based on the results from Model 1 evaluation. The additional Models 2 through 6 were nested in Model 1. To select a best model, the researcher compared the value of chi-square, RMSEA, GFI, AIC, and ECVI. Since Model 6 also illustrated conceptually or theoretically reasonable relationships among constructs as well, it was finally selected as a best model. In the Model 6, the creative dimension of consumer's need for uniqueness had a negative relationship with brand loyalty, while the avoidance dimension of consumer's need for uniqueness had positive relationship. The unpopular dimension of consumer's need for uniqueness and clothing interest had significant positive effects on the brand consciousness. The brand consciousness was significantly related to brand loyalty and brand loyalty to purchase intention.

  • The purpose of this study is to link the Yi tribe's traditional patterns to bag design. Yi tribe is a minor ethic group in China, whose traditional pattern has a high artistic value in that its shapes are diverse and each one has peculiar elegance. Traditional patterns are also indicative of spiritual dept or symbolic stories, rather than being indicative of simple formative beauty. Thus, reorganizing these patterns and applying them artistically to design- in terms of resource utilization- would be significant. Out of all of the Yi tribe's traditional patterns, the cherry blossom_(马樱花), water wave_(水波), sky father and earth mother_(天父地母), pomegranate blossom, triangle, sheep' horn, wisteria vine_(藤条), square and diaper_(四角菱形) and the zigzag_(曲折) patterns were chosen for use during the development of a bag design. This study is based upon document study, including research papers and internet web sites, the point of which was to investigate the form of the traditional patterns, and the creative design process. The design procedure includes these sub-processes: selection, arrangement and color-scheme. In the selection process, the form of the pattern was edited using Adobe Photoshop. The pattern was freely arranged to reflect various emotions. In terms of the color-scheme of the patterns, the colors used by Henri Matisse(1869-1954) in his work were selected and adapted when dyeing the patterns. Subsequently, the final design resulting from these design development processes was applied to the actual production of the bag by using canvas fabric and leather, after which the bag image was proposed using computer simulation. In conclusion, six bag designs were created using traditional patterns from the Yi tribe. Through the processes explained above, this study confirmed that traditional patterns could be widely applied as design motifs and that more sophisticated, modern, and creative designs could be developed based on traditional patterns.

  • The pattern cases for Korean traditional socks are named "beoseonbongip" which means a pouch to keep patterns for making "beoseon". "Beoseon" is Korean traditional socks. This study is to identify characteristics of the pattern cases and to develop cultural products based on the unique characteristics of the pattern cases. One hundred fifty one photos of "beosonbongip" were collected and quantitatively and qualitatively analyzed. Seventy percent of them were made between Joseon Dynasty and 1960s. As a result, most of the collected pattern cases are rectangular and square shapes, red color, and silk fabrics, and sizes of them are from 9cm to 15cm. A few pattern cases with different sizes and colors were also observed. Most pattern cases were made by fixing two among four triangle pieces which made by folding four tips of a rectangular or square cloth and then puting a not or a loop on the remaining triangle pieces in order to open and close the pattern cases. In a small number of the pattern cases, three of the four pieces were fixed and a button, a bead, a broach, or two nots or two loops were put on the other piece for opening and closing. Products such as apparels, bags, pouches, frames, and key holders were made using "beoseonbongip" form and construction method. This shows that "beoseonbongip" is a useful motive for creative product development.
